several species. From the base of the pseudo-bulb, the short 

 scape is thrown out and hangs downwards, in an early stage wholly 

 covered by very large sheathing membranous pale brownish-co- 

 loured imbricated brackets. This scape bears from three to four 

 very large jfcm, of a form difficult, if not impossible, to convey 

 an idea of in words. The 3 sepals are broadly ovate and spread- 

 ing, concave especially below, the margins more or less recurved. 

 Petals oblong-lanceolate, and, as well as the sepals, of a rather 

 dingy yellow colour, mottled, especially towards the base, and 

 spotted with dark sanguineous purple. Lip very large, and of a 

 remarkable shape, divided into three portions, the lower (or hy- 

 pochilium), is very concave and cup-shaped, with a large tooth at 

 its apex, and, within, some raised radiating granulated lines. 

 A middle portion is the " metachilium," it is short, and bears 

 two long curved and geniculated horns, and encloses, as it were, 

 the " epichilmm," a middle lobe of the lip, which is rhomboid and 

 three-toothed at the apex. The whole of the lip is thick and fleshy 

 or rather of a waxy consistency, of the same general ground colour 

 as the perianth, and more or less spotted with purple, the upner 

 and under side however of the " epichilium" is tinged with orange. 

 A great part of this lip is covered by the very large spathulate 

 incurved column, winged at the margin, more or less spotted with 

 purple, and bearing the anthers at the apex beneath. Pollen-mas- 

 ses club-shaped, attached to a curious foot-stalk.
